TIMOTHY H. HUToHI-nson, or GORHAM, NEW-{HAMPSHIRE Specification formingpart of Letters Patent No. 182,759, dated October 3, 1876; applicationfiled June 3, 1875.

To all whom it may concern:

Be it known that I, TmorHY H. Huron- INsoN, of Gorham, in the county ofCoos and State of New Hampshire, have invented certain new and usefulImprovements in Water- Elevators; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to which it pertains to make and usethe same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part ofthisspecification.

Figure l is a side elevation.

Same letters show like parts. I

The object of my invention is to produce certain improvements inautomatic-working water-elevators. It consists in an arrangement ofparts by which a natural falling body of water may be made to raise aportion to a desired point or elevation, as herein described.

My invention may be thus describedz'a shows the pump for forcing thewater. b is the piston, which is operated by the upward and downwardmovement of the lever c, to whlch it is pivoted, as shown. This lever ispivoted to a rocking stanchion, f, and has on one end the weighted boxg, and on the other the water-reservoir h. V

The object of having the lever c pivoted to a rocking stanchion is that,in its upward and downward movement, it will accommodate itself to themovement of the piston, and not allow the said piston to move in any buta true vertical direction.

Near the water-receptacle is the weighted block 6, pivoted in such amanner as to hold the water-reservoir in position when being filled withwater, and when it is filled this weighted block yields to the superiorpressure, and the said reservoir carries its end of the lever 0 downwith it to the tank from which the pump is fed. When it arrives at thelowest point in its descent it strikes upon the upright pin j, on thepivoted frame j, which pin opens a valve, through which the water isdischarged into the water-tank from which the pump is fed.

On the top of the end of the lever to which the reservoir is attached ispivoted the latch 70, provided with the small wheel I, which catchesupon the end of the weighted block 2',

and holds the said reservoir in position until the water in it overcomesthe weight of the block, when it is released and descends to thesupply-tank. I

The purpose of the pivoted frame j is that, should there be any back orwaste water higher than that in the tank from which the pump is fed, itwill rest or float upon it, and cause the pin to be held in suchposition that it will discharge the contents of the reservoir each timeit descends.

m is a lever, provided with a notch, and is fastened to the valve in thewater-reservoir. Its purpose is that, when the valve is raised bycontact with the pin j as it (the reservoir) descends, it will raisethis lever, and the notch will pass over a stud or equivalentprojection, and hold the valve open until the weighted box on theopposite end of the lever c raises the reservoir to a point nearly highenough for the latch to catch the weighted block before described, whenit falls off and allows the valve to close.

a is a lever attached to the pivoted stanchion f, before described, onone end, and to the lower side of the water-reservoir at the other end.The object of this is to insure the reservoir being held in a truevertical position during its descent and rise. 0 is an arm reaching fromthe lever c to the fixed stanchion p, and is pivoted at each end tothese parts, and aids in producing the vertical movement of the piston11 as the lever 0 moves up and down. i

The supply of water can be furnished in any quantity, and can be broughtfrom any distance to any desirable point. The elevator .will work underany head of water, will stop only when all flow ceases, and will startautomatically with the beginning of the smallest flow, and will continueto work so long as the materials of which it is made last.

It will be observed by reference to the drawing that the pivotal pointof the arm 0 to the lever c is forward of the pivotal point of thepiston-that is to say, that itis on the side of the weighted box. 8shows the supply-tank.
